Outline
To analyze the research development trends of telemedicine applications in cardiovascular disease management in low- and middle-income countries based on bibliometric methods.
Research articles related to the application of telemedicine in cardiovascular disease management within middle-and low-income countries were retrieved from the Web of Science database, covering the period from January 1, 1998, to April 30, 2024. Using Excel, VOS viewer, and R software, we analyzed and visualized annual publication volume, regional research intensity, keywords, country citations, and conducted regional disparity and research topic analyses.
A total of 514 articles were included in the study. The number of publications on telemedicine in cardiovascular disease management in low- and middle-income countries showed an upward trend from 1998 to 2023, particularly experiencing rapid growth since 2012. China (21%), the United States (13%), and India (11%) ranked as the top three countries in terms of research output. Among 134 low- and middle-income countries, 57(43%) reported the application of telemedicine in cardiovascular disease management, with the highest research output from China, India, Brazil, Iran, and Bangladesh. The research primarily focused on upper-middle-income (50.3%) and lower-middle-income countries (40.9%). The technological applications were concentrated in disease risk factor control, screening, and diagnosis, covering all stages of prevention. The most commonly used tools included mobile applications and wearable electrocardiogram devices, which have increasingly incorporated machine learning, deep learning, and artificial intelligence technologies in recent years. The target users of these technologies included the general public, patients, and healthcare service providers.
The volume of literature on telemedicine in cardiovascular disease management in low- and middle-income countries continues to grow, integrating into the entire management process of cardiovascular diseases in these regions.However, challenges such as the digital divide due to regional development disparities persist. There is an urgent need to promote the implementation of technology support and economic incentive policies, particularly in African countries, to establish an efficient, safe, and convenient digital cardiovascular disease management system.
